The U.S. Dept. of Energy sponsors a biennial race of solar powered cars called the American Solar Challenge. It's a race that's every bit as competitive as the Indy 500. Engineering students at various colleges compete against each other in a race that starts in Chicago, IL and ends in Claremont, CA. "We used lithium ion batteries in place of lead-acid batteries this year," explains Brian Gilchrist, professor of electrical engineering at the University of Michigan College of Engineering. He is one of the team members for the university's M-Pulse, the car that won the American competition this year. Gilchrist says it is a catalyst for innovation and beneficial to the auto industry. "Automotive manufacturers are looking at the photovoltaic systems, some of which may eventually be applied in hybrid vehicles," he says. The M-Pulse has an all-composite structure for weight reduction. Gilchrist adds that the car's aerodynamic design also helped win the race. This year's victory was especially sweet for the University of Michigan because they beat the University of Missouri at Columbia, last year's race champions. Sponsors of the race include Ford, GMC, MDSI, National Instruments, Keithley Instruments, Loctite, Motorola, and John Deere. For more information, go to www.engin.umich.edu/solarcar.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
